IMPORTANT!
Please read before installation
This air conditioning system meets strict safety and operating
standards.
For the installer or service person, it is important to install or
service the system so that it operates safely and efficiently.
For safe installation and trouble-free operation, you must:
• Carefully read this instruction booklet before beginning.
• Follow each installation or repair step exactly as shown.
• Observe all local, state and national electrical codes.
• Pay close attention to all warning and caution notices given in
this manual.
•The unit must be supplied with a dedicated electrical line.
• Ground the unit following local electrical codes.
• The Yellow/Green wire cannot be used for any connection
different from the ground connection.
• Connect all wiring tightly. Loose wiring may cause overheating
at connection points and a possible fire hazard.
• Do not allow wiring to touch the refrigerant tubing, compressor,
or any moving parts of the fan.
• Do not use multi-core cable when wiring the power supply and
control lines. Use separate cables for each type of line.
When transporting
Be careful when picking up and moving the indoor and outdoor
units. Get a partner to help, and bend your knees when lifting to
reduce strain on your back. Sharp edges or thin aluminium fins on
the air conditioner can cut your fingers.
WARNING
This symbol refers to a hazard or unsafe practice which can result
in severe personal injury or death.
CAUTION
This symbol refers to a hazard or unsafe practice which can result
in personal injury or product or property damage.
If necessary, get help
These instructions are all you need for most installation sites and
maintenance conditions.
If you require help for a special problem, contact our sale/service
outlet or your certified dealer for additional instructions.
In case of improper installation
The manufacturer shall in no way be responsible for improper
installation or maintenance service, including failure to follow the
instructions in this document.
When installing...
... In a ceiling or wall
Make sure the ceiling/wall is strong enough to hold the unit-weight.
It may be necessary to build a strong wooden or metal frame to
provide added support.
... In a room
Properly insulate any tubing run inside a room to prevent
"sweating", which can cause dripping and water damage to walls
and floors.
... In moist or uneven locations
Use a raised concrete base to provide a solid level foundation for
the outdoor unit.
This prevents damage and abnormal vibrations.
... In area with strong winds
Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
... In a snowy area (for heat pump-type systems)
Install the outdoor unit on a raised platform that is higher than
drifting snow. Provide snow vents.
SPECIAL PRECAUTIONS
• During installation, connect before the refrigerant system and
then the wiring one; proceed in the reverse orden when removing
the units.
WARNING
When wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A QUALIFIED,
EXPERIENCED ELECTRICIANS SHOULD ATTEMPT
TO WIRE THIS SYSTEM.
When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare
and union tubes before connecting them; screw by hand and
then tighten the nut with a torque wrench for a leak-free
connection.
• Check carefully for leaks before starting the test run.
NOTE:
Depending on the system type, liquid and gas lines may be either
narrow or wide. Therefore, to avoid confusion, the refrigerant
tubing for your particular model is specified as narrow tube for
liquid, wide tube for gas.
• Do not supply
power to the unit until all wiring and tubing are
0.8180.531.00
05/2007
completed or reconnected and checked, to ensure the grounding.
• Highly dangerous electrical voltages are used in this system.
Carefully refer to the wiring diagram and these instructions when
wiring.
Improper connections and inadequate grounding can cause
accidental injury and death.

When servicing
• Turn the power OFF at the main power board before opening
the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after the work, remembering to check that no
metal scraps or bits of wiring have been left inside the unit being
serviced.
• Ventilate the room during the installation or testng the refrigeration
system; make sure that, after the installation, no gas leaks are
present, because this could produce toxic gas and dangerous
if in contact with flames or heat-sources.

Insulation of Refrigerant Tubing
IMPORTANT
Because capillary tubing is used in the outdoor unit, both the wide and narrow tubes of this
air conditioner become cold. To prevent heat loss and wet floors due to dripping of condensation,
both tubes must be well insulated with a proper insulation material.
The thickness of the insulation should be a min. 8mm.
CAUTION
After a tube has been insulated, never try to bend it into a narrow curve
because it can cause the tube to break or crack.

7. FUNCTION
7-1 Diagnostic
With this feature is possible to have a visual signal that a trouble is occurring.
This mode is always active and the signalling is made through the display board LEDS .
In case of no troubles the LEDS status follows its normal function.
The detected troubles are showed to the user/technician using the 3 or 5 leds of the indoor unit receiver
and the 5 leds on the outdoor pcb. For each fault there are different effects upon the operation of the A/C:
NOTES
The troubles are showed according to a priority list that is in case of more than one trouble present,
is always showed, at first, the one with the highest priority (3 2 1 etc).
Sensor damaged means a situation where sensor is short-circuited or opened.
In case of damaged sensors, the system (CM, FMO, FMI etc), if in OFF state, does not start.
EFFECTS
system does not operate
as soon as fault is cleared,
the system automatically
re-start after 3 min.
during this time,
the signalling is showed
